I am getting sensative nipples and some slight water retension so I figured it was time to break out the Letro. I have the liquid form, 2.5mg/ml.....so my question is in a 1ml dropper how much would be .25mg? I took a full ml last night thinking it was dosed at .25ml then realized it was actually 2.5mg. I want to start with a low low dose so.............a half ml would be 1.25mg and half of that would be .625mg right? So im thinking like 5 drops from a 1ml dropper will be sufficient?
